Rust on washing machine's drum

The reason for rust on the drum is that foreign objects made of iron have been in the machine and created a coating of rust.

If this is rust film, you can clean your machine with a suitable agent for removing rust. Agents which can be used to remove rust are e.g. citric acid powder, machine cleaner, hob cleaner or steel polish.

If there has been any metal in the machine, which has been spun round and scratched through the surface of the drum, this unfortunately cannot be removed and the drum must be replaced.
